Abstract: Case 7656(2) ABSTRACT OF THE DISCLOSURE                       DESULPHURISATION OF OIL     A process for desulphurising hydrocarbon oils comprises the steps of (1) treating a sulphur containing hydrocarbon oil with a catalyst consisting essentially of an aqueous acidic or neutral solution of a molybdenum, tungsten or vanadium heteropolyanion and an oxidant under conditions such that the sulphur is oxidised and (2) separating the oxidised sulphur from the treated hydrocarbon oil.  Preferred catalysts include those heteropolyanions derivable by ionisation of an acid having the general formula He(XkMnOy) where X is selected from phosphorus, antimony, silicon, germanium or boron; M is selected from molybdenum, tungsten or vanadium; k is from 1 to 5; n is from 5 to 40; y is from 18 to 62 and e is the valance of the (XkMnOy)e- anion.

Patent CA-2054781-A1 (CA)
Inventor: GADELLE CLAUDE
IPC: E21B43/02
Filed: 1991-11-01
Abstract: Précis de la divulgation : La méthode concerne l'application à un puits dévié d'un procédé connu de consolidation par polymérisation in situ d'une substance liquide injectée jusque dans une zone à consolider par un tube d'injection, par interaction avec un gaz G réagissant injecté à sa suite. Pour limiter la zone d'intervention et bien répartir la substance et le gaz sur toute cette zone, on utilise en combinaison un tube dont la paroi est pourvue d'ouvertures, sur toute sa partie terminale, un packer de confinement et un élément de séparation solide déplace dans le tube à la suite de la substance liquide, par le gaz réagissant, qui empêche toute interaction de celui-ci avant qu'il ne parvienne à la zone à consolider. L'injection du mélange liquide comporte des phases successives de circulation entre l'intérieur du tube et l'annulaire entre lui et le puits et de forçage pour le faire bien pénétrer dans la formation. Elle est généralement précédée d'une phase d'injection de produits solvants. Application à la consolidation de puits horizontaux produisant des effluents pétroliers. Fig. 1 à publier.

Abstract: ABSTRACT OF THE DISCLOSURE       The invention relates to a device for the reprofiling or burnishing of a rail on a railway track and comprises a rigid frame (10) connected to the framing of a railroad vehicle by lifting means allowing a light running of the railroad vehicle and at least one grinding unit (11, 12). Each grinding unit (11, 12) is mounted on a support (13) in such a way that it can displace itself linearly to move the grinding wheel towards and away of the surface of the rail 1,2 to be grinded.  The grinding wheel's (11) axis is located in a plane perpendicular to the longitudinal axis of the rail (1, 2) but does not intersect it so that the contact line of the grinding wheel (11) with the surface of the rail (1, 2) will be comprised in a plane per-pendicular to the longitudinal axis of the rail.  The sup-port (13) is mounted on the frame (10) by translatory mo-tion means allowing the said support to move itself trans-versally regarding the frame (10). The support (13) com-prises at least one support roller (17) and support means (18), connecting this support (13) to the frame (10) and tending to apply this support roller (17) against one of the sides of the rail (1, 2) at the immediate proximity of the grinding unit (11, 12).

Patent CA-2068804-A1 (CA)
Inventor: SCORTICHINI CAREY L
IPC: C25B9/19
Filed: 1992-05-15
Abstract: An electrolytic cell for the labeling of proteins, peptides and other organic molecules employs a cathodic half cell and an anodic half cell, where a porous working electrode is located in one half cell and a counter electrode is located in the other of the half cell, the two half cells being divided by a separator.      A reference electrode located in the half cell containing the working electrode, and placed outside the current path between the working electrode and the counter electrode confers precise control of the working electrode potential, which allows the maximum rate of labeling to be achieved while minimizing oxidative damage to the protein, peptide or organic molecules.      Saturation of the working electrode with non-radioactive label coupled with a ratio of working electrode surface area to volume of half cell containing the working electrode between 0.001 to 10 cm-1 minimizes the problem of loss of activity of radiolabel due to adsorption on the working electrode.

Title: Needle park
Inventor: ALPERN MARVIN
IPC: A61B19/00
Filed: 1992-07-06
Abstract: A needle park for a package that holds one or more surgical needles and sutures has a generally planar base and two collinear walls that are perpendicular to the base. A cutout near one end of the first wall separates an end section of the wall from the base and separates all but a top segment of the end section from the rest of the wall. The second wall is separated from the end section by a gap. The end section and top segment of the first wall form a hinge that permits a needle to be held in the gap between the walls. In an alternative embodiment, both walls have cutouts and resultant hinges, thus permitting the needle park to hold needles of larger diameter. Preferably, the material of the needle park is a moldable thermoplastic. The needle park is inexpensive to fabricate and permits a needle in a broad range of diameters to be held simply and securely.

Title: Oil recovery system for low capacity operation of refrigeration systems
Inventor: STARNER KEITH E
IPC: F04C29/02
Filed: 1991-12-16
Abstract: An oil recovery system for refrigeration apparatus of the type in which an oil lubricated screw compressor is oriented with a suction inlet in communication with an evaporator chamber positioned under the compressor so that under conditions of low capacity compressor operation, lubricating oil may fall from the compressor through the suction inlet thereof and into the evaporator. The recovery system takes advantage of an existing suction distribution tray in the upper region of the evaporator chamber of such systems, normally used to assure distribution of gaseous refrigerant to the suction inlet of the compressor, by removing oil dropping into the tray and returning it back to the compressor. An existing by-pass eductor loop for returning liquid refrigerant from the evaporator to the compressor is extended by a valve controlled branch to a second eductor for withdrawing the oil from the tray and returning it to the compressor. The valve is controlled so that the oil recovery system is disabled at normal compressor capacity levels.

IPC: F28F1/00
Filed: 1992-10-20
Abstract: A fuel-fired condensing furnace is provided with a specially designed heat exchanger structure having a metal primary section and a plastic secondary or recuperative section.   The primary section is defined by a horizontally spaced series of identically sized,  vertically serpentined metal combustor tubes adapted to receive a throughflow of a burning fuel-air mixture discharged from the furnace burner section.  Each tube has an essentially straight inlet combustion section sized to permit essentially complete combustion therein of the burning fuel-air mixture received by the tube, and a plurality of vertically spaced horizontal heat transfer sections that are horizontally flattened and narrowed to enhance their combustion heat transfer to supply air being forced upwardly through the furnace housing.  The heat transfer efficiency of the flattened tube sections is further enhanced by forming spaced series of indentations in their flattened opposite side walls to create combustion gas flow turbulence within their interiors, and air flow turbulence along their exterior surfaces.
